10 distinct techniques documented for this family, organized by ATT&CK tactic.
In May 2017, Palo Alto Networks Unit 42 identified a limited spear phishing campaign targeting various individuals across the world. The threat actor leveraged the CVE-2017-0199 Microsoft Word Office/WordPad Remote Code Execution Vulnerability with carefully crafted decoy content customized for each target recipient.
Our research showed that the spear phishing emails came from multiple compromised email accounts tied to a legitimate domain in North East Asia. We believe that the threat actor hijacked an existing, legitimate in-progress conversation and posed as the legitimate senders to send malicious spear phishing emails to the recipients.
Then using the Windows API ShellExecuteW() and a hard-coded argument ‘abai’, the malware executes the decoded payload.
The C2 server responds with a Base64 encoded PowerShell script which in turn downloads two fake image files that contain embedded PE binaries and a JavaScript file which extracts the embedded PE binaries onto the victim host.
After a successful exploitation, it sets persistence in the registry with the appropriate command line argument to execute the second stage payload... HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\ key name: runsample key value: "[CURRENT_EXECUTION_PATH] help"
